MECHANICAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 488,260, dated December 20, 1892.

Application tiled August 23, 1892. Serial No. 443,864. (No model.)

.To @ZZ whom it may con/cern;

Be it known that I, GEORGE F. BERG, a citizen of the Unit-ed States, residing at De Vitt, in the county of Saline and State of Nebraska., have invented a new and useful Mechanical Motor, of which the following is a specica` tion.

This invention relates to mechanical motors; and it has for its object to provide an improved mechanical motor adapted particularly for pumping purposes; but one which can also be advantageouslyemployed for other analogous purposes requiring a reciprocatory movement.

To this end the invention contemplates certain improvements upon ordinary weight motors in use. Y

With these and many other obj ectsin view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully understood, illustrated and claimed.

In the accompanying draWings;-Figure 1 is a top plan view of a mechanical motor constructed in accordance with this invention. Fig. 2 is a front elevation of the same. Fig. 3 is a rear elevation thereof. Fig. 4 is a detail in perspective of the sectional vibrating lever. Fig. 5 is a detail view of the intermittently rotating strike wheel.

Referring to the accompanying drawings A represents a suitable frame in which are mounted the shafts B and B respectively. The shaft B carries a drum C upon which is adapted to be wound the rope or chain c, which passes therefrom over the guide pulley D supported above one end of the frame A. Said rope or chain has connected to one end thereof the weight E which unwinds the rope or chain from the drum and communicates motion to the shaft B which in turn drives the spur wheel F, fastened thereto. The spur wheel F meshes with the pinion G, upon the adjacent shaft B', which shaft also carries the spur wheel g, which latter wheel is adapted to mesh with the small cog wheel or pinion g', upon one end of the winding shaft H, which shaft is journaled in the uprights h eX- tending above the main frame A. Loosely mounted upon the winding shaft H is the intermittently rotating strike wheel I, carrying upon one face thereof:` the spring-pressed pawl i, adapted to engage the adjacent ratchet wheel e, fixedly secured to the shaft H, so that while the drum is unwinding the rope or chain thereon, or at least is revolved by the Weight itself, motion will be communicated through the train of gears to the wheel I to rotate the same intermittently by the means hereinafter described. One end of the shaft H is extended in order to accommodate a winding crank to draw up the Weight and wind the rope or chain upon the drum, the pawl land ratchet device upon the winding shaft allowing the saine to rotate without turning the wheel I or interfering with the other mechanism of the motor.

A sectional vibrating lever J has its connected ends pivotally mounted upon the winding shaft H, directly in front of the strike wheel thereon, one of the lever members being provided at a point adjacent to the shaft H with the adjustment slot j, through which passes the set screw j', adapted to engage the inner end of the other lever member so as to provide means for adjusting said slotted member with respect to the other lever member in order to provide for the proper operation of the motor. The lever members may be designated as ,i2 and jg respectively. Pivotally secured to the outer end of the lever member j2, is the depending-swinging lever arm K, carrying upon its lower end and one side thereof the contact roller L, while the upper end of said lever near its point of pivot is provided with an off standing strike lug 7c, that is adapted to be struck at regular intervais by the strike pins M secured tothe front face of the strike Wheel I, and projecting therefromin a concentric series. The contact roller at the lower end of said lever arm is adapted under the force of the strike pin bearing against the strike lug thereof, to travel against the curved guide plate N secured to the frame adjacent to the strike wheel. The said guide plate N is provided with a lower reduced guide arm n, while adjacent to the same is pivoted the spring-pressed guide dog O which is normally held against the guide plate Nin a line with the main curved contact face or track, and off from the reduced guide arm n IOO thereof. Now it will be readily `seen that one of the strike pins M bearing against the offstanding strike lug k will hold the contact roller Lagainst the guide plate and guide dog, until the same has passed over the lower pivoted end of the guide dog, at which moment the said contact roller will be thrown against the reduced guide arm n, between the same and the dog O, and the olf-standing strike lug clear of the strike pins to place the lever arm ina proper position to be raised. To the outer end of the lever member j2 is also pivotally 'connected t-he upwardly extending connecting arm p, which is connected at its upper end to the rock arm p', iixedly secured at one end upon the oscillating pendulum shaft Q. The said pendulum shaft Q is mounted in suitable supports q, and carries upon oneend thereof the connecting arm R, which may be connected with -a pump rod or other device to be reciprocatd, while to the other end of said shaft is secured the swinging weighted pendulum S. rIhe said pendulum S is provided with an inwardly projecting pin s, which is designed to be engaged by the notched controlling lever 'I pivoted to a suitable point of attachment, so as to hold the pendulum out of a vertical line in order to provide means for stopping and starting the motor at will.

Pivotally secured at one end to the upright VU near the outer end of the lever member je',

is the stop lever arm V. The said stop lever arm V is similar in construction to the lever arm K and is provided at its upper end with a contact roller fu, while at its lower end, near its point of pivot, the same is provided with an off-standing strike lug n which is adapted to be engaged by one of the strike pins M, to stop the strike wheel I at the very moment that the contact roller L of `the lever arm K clears the lower pivoted end of the guidedog O, and leaves the arm K free to ascend under the weight of the pendulum, which will continue to oscillate the shaft Q after the strike wheel has been thus stopped, and thereby draw the Contact roller between thev guide arm n and the spring actuated guide dog O, which dog yields to the upward pull of the contactroller, and allows the same to pass onto the main portion of the guide plate N to bring the strikelug 7c under the next strike pin. Then said guide dog` springs back into alignment with the main portion of the guide plate so that the roller L can again commence its downward travel when the stop arm V has released the wheel I.

As stated, when the contact roller L has cleared the lower pivoted end of the guide dog, one of the strike pins engages the strike ,lug of the stop V which holds the strike wheel fast. The tendency of the wheel I to turn holds the contact roller of said stop lever arm V against the stop or guide plate W, adjacent to the upper end of which is pivoted the spring actuated guide dog X, the lower end of which normally contacts with said guide plate to form a continuation thereof and a i face over which the roller o' bears. The wheel I is held fast while the pendulum is raising the lever arm K, as already described, up to the next strike pin. This movement lowers the outer lever member js, and causes the contact-roller of the stop arm V to pass over the guide dog X. When the contact roller of said stoparm reaches the top of the guide dog X, the same is thrown thereover by the strike wheel, which thus releases itself from the stop arm and again lowers the other end of the lever as already stated. The contact roller of the'stop arm V has now passed between the upper end of the plate W and the dog X, so that as the lever member t7'2 lowers, the other lever member js rises and allows the contact roller of said stop arm to pass back to its proper position for catching and holding the next strike pin as will be. readily apparent.

By the adjustment of the sectionalflever as already described, it can be readily seen that the two members thereof can be so set that the levers arms K and V will be placed into engagement with and disengagement from the pins ofthe strike wheel at the proper time.

Having thus described my inventionfwhat I claim and desire to secure by Letters Patent is;-

l. ln a mechanical motor, the combination with a train of gearing; of an intermittently rotating strike wheel connected with said gearing, and having a concentric series of strike pins near its edge, a sectional adjustable vibrating lever arranged adjacent to and mounted to oscillate on the same shaft as said strike wheel and moved in one'direction by the same, stop and releasing devices carried by and arranged at opposite ends ofsaid le ver, and apendulum shaft connected with one end of said lever and adapted to move the same in the other direction, substantially as set forth.
